Specification of Letters Patent.

To all whom it may concern 1de it known that I, d. HENRY B'RADY, citlzenof the United States, residing at the city of Louisville, inthe countyof J eiferson .and State of Kentucky, have invented certain new anduseful Improvements in Paper Drinking-Cups, of which the following is aspecification.

This invention relates to improvements in paper drinking cups, and hasfor an objectv view of the blank from which my improved cup is formed;Figs. ,2 and 3 plan views of the blank in progressive stages of folding;Fig. 4r, a plan View of the cup completely folded; Fig. 5, a rearelevation of the cup as opened for use, showing a strengthening rib, inexaggerated size; Fig. 6, a perspec' tive of the cup lopened for use,the handle being turned down to hold it in that position.

ln the drawing -1'- indicates a semicircular piece of suitable paper,divided/on the line -2- into quadrants Q3- and f4- Which are provided ontheinffree straight sides With aps '54- and ..6-. The proximate ends ofthe flaps are rounded oif formling .a notch JZ-that extends in towardthe body of the blank to a point spaced therefom a distance at leastequal to the thickness of the material. It is to bevnoted that it isessential that the notch does not extended entirely to the boundary lineof the body of the blank, otherwise the point of the cup would not becompletely closed. Each of the flaps extend beyond the circumferentialboundary of the blank and serve to form part of tabs, or-extensions, -8and -9--,

' the other part of the tab being integral with the body of the blank,said tabs when super-y imposed, in folding up the cup, forming a handle-10- therefor.

ln forming the cup, the lap' vis folded'` over upon the quadrant 3 andan adhesive applied to the, then, exposed faces of the aps, as indicatedAin Fig. l2.'. Awaterproof straln.

adhesive will suice to hold the cup for the temporary service for whichit is intended. The quadrant 3, together with the gummed flap 5, is nowfolded over orrthe, quadrant All, as shown in Fig. 3, the adhesive onthe flap 5 contacting with and adhering 'to the .quadrant 5; the gummedflap dis then folded over upon the back of the quadrant, the adhesivethereon holding firmly. The cup is now completely formed as shownin Fig.4. The superimposing of the tabs 8 'and 9`serves to form a handle --10of ping of the flap 5 on the interior, and of flap 6 on the exterior ofthe blank forms a reinforcement at the point. of juncture of the blank,as does a rib l1-f that is formed on the junctureline of the flap' withthe body of the blank, said reinforcementsfserving toy strengthen thecup at the point of. greatest lt will readily be seen that .by theforegoing construction I have produced a cup ofA maximum capacity fromay minimum quantity of material. f

-The 'cupis usually vended in the shape shown in Fig. 4, and forsenviceis opened up, :pressure being exerted on the folded edges for thatpurpose, and the handle turned down in a plane with the .top of the cup,thel chord subtended by the handle on the circumference ofv thetoppreventing it Having described my invention so that any one may make anduse the same I claim 1. A blank for making a paper drinking cupcomprising a semi-circular body divided bya radial score into quadrants,said quadrants provided on their free sides with flaps the proximateends of which are rounded of forming a notch'that extends towithin aspaced distance of the boundary of the blank, said Haps extending beyondthe circumferential boundary. ofv the blank.-

2. A blank for making a paper drinking cup comprising a semi-circularbody divided by a radial score into quadrants, said quadrants providedon their free sides with iaps the proximate ends of which are roundedoff forming a notch' that extends to within a spaced 'distanceof theboundary of the blank. y

3. Acone shaped drinking "cup formed of a semi-circular blank, gummedflaps formed integral with the blank and adapted toad- =hererespectively to the interior and exte' rior surfaces of the cup, and ahandle projecting beyond the margin of the cup, 4said handle comprisingsuperimposed extensions of said fla-ps and said blank.

' 4. A blank for making a paper drinking cup, comprising a semifcircularbody, the

ybrought to conical form with said tabs in registration, and gummed apswhereby. 2O said lquadrants are adapted to be held together. 6L A coneshaped drinking cup formed of a semi-circular blank, gummed-laps formed.integral with the blank and adapted to ad- 25 here respectively to theinterior and exterior surfaces of the cup, a handle projecting beyondthe margin of the cup, said handle comprising superimposed extensions ofsaid flaps and said blank, and a strengthening 304 rib extending fromthe-apex of the cone .to the tip of the handle, over the juncture lineof the blank.
